  * @description
  * Modifies the default behavior of the html A tag so that the default action is prevented when
- * the href attribute is empty.
+ * the a href is empty or it contains `ng-click` directive.
  *
  * This change permits the easy creation of action links with the `ngClick` directive
  * without changing the location or causing page reloads, e.g.:
  * `<a href="" ng-click="model.$save()">Save</a>`
